How to check water level in battery? An RV battery is a useful power source for the recreational vehicle, ensuring you’re still getting your energy needs even while away from home. They are also used during family camping over an extended period.

These RV batteries store energy that would permit appliances, generators, vehicles or even tools used in the medical, logistics and construction, emergency responses and military operations to power and fulfill their function.

These batteries should be properly taken care of in the most appropriate and suitable manner, or they will give you headaches when malfunctions occur.  If maintained properly, they are reliable power sources during dry camping or planning on boondocking.

But besides being educated on what batteries to use for their mobile home and their purpose of utilizing them, RV-ers must be knowledgeable on checking the water level in the battery.  Let’s discuss more about it in the following. But first, let’s define what these batteries are and why they’re suitable for an RV.

What are deep-cycle batteries and why are they the best choice for RV’s?


According to professionals from RVneed, the RV Deep cycle battery is alluded to as the measure of consistent current that is being given throughout an all-encompassing timeframe where your battery is the fundamental source of energy, controlling and running different RV Electronics.

It is usually being compared to lead-acid battery that you can find in boats or golf trucks. It is somewhat similar with car battery due to its composition and purposes; however, deep-cycle batteries are ones which have thicker plates that allow them to be discharged and recharged repeatedly, eventually producing a steady amount of current power throughout a more extended timeframe. Unlike car and standard batteries that make a great deal of current throughout a brief timeframe.

Similarly, as with all RV parts, to guarantee you benefit from your batteries, you should finish routine support and maintenance. By checking consistently to see that everything is in appropriate working request, you extend the life span of your RV battery and save money in the long haul.


One of the main RV battery support tips includes checking the liquid degrees of every one of the batteries on your unit. In the following, we’ll discuss the fundamental upkeep or maintenance tips that you need to assess a 12-volt lead corrosive battery for liquid levels and top it off if any terminals are coming up at a low run.

Yet first and foremost, experts recommend safety measures beforehand. Primarily, utilize distilled water only and make sure to have in store one or more bottles of it in your vehicle. Next, wearing of gloves and googles are a must; jewelries are to be removed too. Also, when working around batteries it must be noted to not smoke nor to have an open flame before starting.

  1. To check whether the water level is underneath the plates, otherwise known as fill-well or split-ring, look at the battery itself.
  2. On the off chance that it is, add distilled water for the plates to be covered. (Excess water dangers the needed electrolyte solution of acid and water that will likewise cause corrosion and overflowing.)

Note: At the point when you add water to a battery you just fill the cell to 1/8 inch beneath the lower part of the fill-well or split-ring. If you look inside the battery cell you will see a plastic ring that reaches out down inside the cell around 1 inch. This is the thing that is alluded to as the fill-well or split-ring. The electrolyte arrangement in lead-corrosive batteries is a combination of sulfuric corrosive and water

  1. A charged battery gives off the most accurate and precise water level readings, so charge your battery.

How they’re utilized, how well they’re kept up, the discharging and re-charging method, and how they are put away, all add to how long it would live. Batteries are completely charged when finished discharging from 100% below to around 50% and afterward energized back to 100%.

A significant factor to battery’s lifespan is on how profound the battery is appropriately cycled over a period. On the off chance that the battery went to 50 percent regular, it will keep going twice the length it would on events that it is charged to the percentage of 80.


Remember this when considering the amp hour rating of a single battery. This ampere hour rating is truly sliced down into half since not fully discharging the battery prior to energizing it is what RVers usually prefer. The future of a battery relies upon how quick a discharged battery is charged. An instant respond of charging the battery again is the better.

Buying tools means taking care of it; and taking care of it means valuing it.  The life span of the RV batteries is in your hand.  So, begin having your own comprehensive understanding of it and bestow a good ongoing care, because one way or another, these things supply your energy needs while camping or driving your RV.
